HOW IT WORKS
The Automatic Door Bottom is the cornerstone of Legacy Manufacturing’s impressive product line. This product, also called an automatic drop seal, is used on the bottom of a door to provide protection from fire, smoke, noise and other threats to the life safety and comfort of building occupants. When the door is closed, a plunger is mechanically pushed against the frame, allowing a spring mechanism within the door bottom to be activated and pushed downward. This process allows a seal to be activated, and the rubber insert creates a uniform, continuous seal along the bottom of the opening. Our Automatic Door Bottoms are one of the growing products here at Legacy Manufacturing. All our products are designed and developed in New York, USA. We here at Legacy ensure the best products at the most sensible prices. Scroll down to view our list of Automatic Door Bottoms.
